So I've driven a vantage with one. Agree with the better engagement and driveability.

My question is why, or what is it that allows (subject to opinion) it to last longer than oem in ss1/all ss cars.

Trying to justify the possibility of BR upgrade more;)

Does anyone know for sure yet how long they last? not been around long enough have they ?

I think you may need to come back in 10 years and ask the same question again, we are barely getting any meaningful stats out of the original 10 year old cars clutch life.....

As far as I can tell, given that the twin plate is the same unit that goes into the V12VS & one-77 it can take far more power & torque than the OEM , ergo it doesn't slip & therefore lasts much longer. I'm not a mechanic but I understand it grips the clutch plate from both sides rather than just one (though I.will probably be corrected by those in the know, Mike from BR?) I've seen 50k banded around on forums but as you point out, they aren't any old enough to prove or disprove that comment.

It's hardly likely to ever read published stats from an approved source about clutch life, is it? So subjective reports is all there will ever be, and with about 15k cars in U.K and this forum probably attracts up to a thousand posters and readers, this forum is far from the big picture too. But...

After seeing quite literally 1000's + owners over last few years, I have seen a freak abuser burn a clutch in under 5k miles and I have seen a freak pull away so gentile user extent eek out 55k+ miles.

The norm is between a window of 30-40k miles where symutaniously the un heat treated flywheel has warped which means ever decreasing friction plate over heat / wear to limit due to reduced surface contact because of the flywheel warp. I have seen many a city car with much greater number of clutch actuation at 35k miles have fine friction plate and flywheel but worn pressure plate / fingers due to number of uses. There are just too many user variables to precisely define a norm, but in any route to wearing out a single plate clutch, 35k is a popular mileage to result in needing a change.


Based on the engineering and design of the parts, I don't see any data driven comment which could ever suggest that in principal a twinplate clutch will last the same or less than a single plate clutch, it has to last longer - although if you have some data, that would be a great read! But what really proves the twinplate lasts longer than singleplate is the same subjective analysis of V12 owners cars where twinplate is OE. Except for original DB9 twinplate because that was not best design and has been superseded, I have yet seen a twinplate V12 car needing clutch change based on outright wear, combined with the weekly clutch changes seen on singlplate V8! It's rare to see mileage on V12V, DBS reach 40k + yet, but in next 5 years when the glut of those cars are + 50k and on original clutch, you will have the subjective data you need to convince yourself the twinplate lasts longer. But based on volume of cars I see and the principle behind the engineering, I already know the answer to your question - no comparison, any twinplate will outlive singleplate

Here's a good question for you too - what benefits to the ownership and driver experience do you think lead to the rationale of the factory releasing a twinplate kit of their own for all V8's after first appearance of a twinplate on a production V8 for GT8?

Here's another question. Twinplate V12V clutch from factory is cheaper than singleplate 4.3L V8 (when buying just clutch part), doesn't that make it madness not to refit when worn with twinplate? If price and longevity didn't clinch it, to those it cares too, the interaction with gearbox and driving pleasure is in different league with twinplate compared singleplate.

Based on twinplate better life, cheaper cost (compared 4.3L singleplate), better driving interaction, can you remind me the attributes you champion the singleplate ??

Ok so what sort of figure am I looking at for the upgrade on my v8 vantage?

Im not championing anything or suggesting a dual plate clutch will not last as long or longer...just saying no-one really knows...it *should* last longer, and hopefully that extra life, and other advantages will offset any additional cost.

To be fair, I dont think its any more expensive than an OE clutch from a dealer, so why wouldnt you fit an upgraded part if you intend to keep the car ?

My single plate OE clutch that went in the car in Dec 2005 lasted until 73K miles in 2015, the dealer said it was the highest mileage they had heard of when I traded the car in recently at 80k miles. Must have had a good one, I hope the clutch in my later Dec12 car will last as long smile

Be interested to know a rough figure too, and if I'd be able to get it sent to Australia. I'm still on 5200 miles / 8000+km tho so still contemplating whether to wear this clutch out first or if I'd Benefit from a twin plate now if I'm planning to keep the car.

Also would it be easy enough for a competent local mechanic to fit it?

Thanks

I would also be interested to know if the BR twin plate clutch and fly wheel can be sent down to Australia. I am sure other V8V owners down under will also be interested.
My V8VS has 11,000kms and seems fine.
I guess the other question is, would the AM dealer fit the V12 twin plate clutch to the my car if needed?

And for this reason only I had one fitted to my manual DB9 during Project 'Blofeld'....
